Schoolboy Jonah Mowry holding up postcards that spell out his struggle with self-harm made the top of the viral video chart this week.

A choked-up audience watched as Jonah wiped away tears, telling millions how scared he was entering Year 8, feeling depressed and considering suicide.

Also trending is a much chirpier Jonah sitting with his friend giving viewers a much better picture of his scars and making fun of people who call him gay: "Hellooo of course I am" he tells the camera.

Called: (HAI DAIR) Was Jonah Mowry lying? You decide. Maybe he was lying, maybe he wasn't, but as many psychologists point out: suicidal feelings are often temporary and in a odd sort of way this happier video should further anyone's resolve to fight bullies even more.

Also inspirational is the video of a very fit 60-year-old man, whose bulging biceps and six pack would put a man half his age to shame. Check out Herbet Bowen from the Lower East Side Of New York, who gives his birth date as 31 December 1950. "That's how I wanna be when I grow up" says the man filming. Couldn't agree more.

Christmas related viral videos are also trending with a prankster snowman and Harvey Nichols ‘walk of shame’ Very tongue in cheek, and also dare it be said, absolutely fabulous?

It’s not a polar bear in the bath, its Casper the dog, lying belly up, his stomach pampered with soapy suds. Probably the most passive pooch you've ever seen.
